我遇到了在我的 MBP 作业中检索主存储库之前检索共享库的问题。在我的常规管道和自由式工作中，情况并非如此。因为 Jenkinsfile 共享库方法尝试从主存储库读取 Xcode 的版本，所以 MBP 作业失败并出现以下错误。这是可以理解的，因为存储库尚未签出。这在常规管道作业中非常有效，我可以在常规管道作业的日志中看到在共享库之前发生轻量检出。在 MBP 中，有没有办法强制在共享库之前签出主存储库？

我花了一段时间才发现的解决方案是使用 GitSCM 插件 DSL 类和方法来公开 MBP 作业配置中定义的 git url 和分支。这两个对象允许您在 checkout 函数调用中使用 GitSCM 稀疏检出并指定特定文件或文件目录。不需要 curl 或 wget 或凭据插值。确切的命令语法如下：

此代码允许您签出共享库中的单个文件，该文件包含在配置作业的 Jenkinsfile 中的节点块之前调用的代码。

def scmUrl = scm.getUserRemoteConfigs()[0].getUrl()
def branch = scm.getBranches()

checkout ([
  $class:'GitSCM',
  branches: branch,
  doGenerateSubmoduleConfigurations: false,
  extensions: [
    [
      $class: 'SparseCheckoutPaths',
      sparseCheckoutPaths: [[path: '/myDirectory/singlefile.txt']]
      ]
  ],
  submoduleCfg:[],
  userRemoteConfigs: [[url:scmUrl]]
])
